United States Patent O RAILWAY CAR DOOR POST Richard P. Molt, Olympia Fields, Ill., assignor to Standard Railway Equipment Manufacturing Company, Chicago, lll., a corporation of Delaware Application May 25, 1956, Serial No. 587,264 4 Claims. (Cl. 10S- 409) which the inside lining may benailed, as Well as any grain doors. Repeated nailing causesV the blocks to split and splinter, and to replace the same with a new block requiresremoval of the insidey lining.

It is the principal object of my present` invention to provide a door post so formed that the block to which the grain doors are nailed may be conveniently removed without the necessity of removing the car lining first.

In the drawings, forming part of this application, and wherein` like reference characters indicate like parts:

Figure l is aview of the inside of a car at the door opening in one wall thereof illustrating grain door boards covering the lower area of the door opening.

Figure 2 is a perspective view of the retainer strip for holding the woodnailing strip in place within the door post.

Figure 3 is a perspective View of the wooden nailer strip.

Figure 4 isa cross sectional view on line 4-4 of Figure 1.

Figure 5 is an exploded View, similar to Figure 4, showing howthe wood nailing strip may be easily removed from the door post.

Figure 6 is a side view of a portion of the door post structure of the invention.

Figure7 is a view similar to Figure 4 of a modified form .of the invention.

Figure 8 is a section on line 8 8 of Figure 7.

Figure 9 is a cross sectional View of a modified form of retainer strip.

Figure l0 is a view similar to Figure 4 of a further modified form of the invention, utilizing the present A.A.R. door post .as part of the structure.

Referring now to Figures l to 6 inclusive, the fioor of the car is indicated at 1 and the doorway in one wall of the car is indicated at 2. The door posts which form the vertical margins of this door opening are shown at 4 and 5 and each extends from the car side sill 6 to the side plate, not shown, as is common. Each door post comprises a hollow rectangular metal pressing consisting of a pair of parallel spaced flanges 6 and 7 positioned transversely of the car wall, joined together by a web 8 parallel with the wall. Flange 6 is provided with a reange 9, and the flange 7 is also provided with a similar but shorter reange 10. To the `outer surface of ange 6 are secured a plurality of vertically spaced stud bolts 11 which pass through corresponding holes 2,884,874 Patented May 5, 1%59 ice in the vertically disposed nailing post l2 and held securely in place by the nuts 13. The outer sheathing of the car is shown at 14, the end margin of which overlaps the web 8 of the door post and is secured along its edge thereto. Overlapping the end margin of the sheathing 14 is one leg 15 of an angle, the other leg 16 of which is turned outwardly coplanar with flange 7 of the door post and to which one part 17 of the door weather strip is secured.

A grain door nailing post 20 is disposed vertically within the door post 4. One corner of the inner face of this door post 2f) is rabbeted as at 21 to fit behind the refiange 10, and the opposite corner is also rabbeted as at 22 to receive the hereinafter described retaining strip 23. In width the post 20 is approximately equal to the distance between the flange 6 and the edge of the reflange 10, so that the post may be moved laterally as shown in Figure 5 and then moved outwardly of the doorpost for complete removal. For convenience in fitting the nailing post within the door post, several of the corners of the wooden post 20 are canted as shown. To hold the wooden post within the door post there is provided a retaining strip of metallic material 23, one vertical edge of which rests within the rabbet 22, and the opposite vertical edge is coplanar with the edge of reilange 9. The strip 23 rests atwise against refiange 9 and is screwed thereto by a row of screws 24. A vertical edge of the car lining 25 abuts the edges of the reflange 9 and the strip 23 and the lining is secured to the nailing post 12. Clips 26 are secured in vertically spaced relation along the inside of the strip i3 and are located so as to project within the door post between the nailing post 20 and the flange 6, when the strip 23 is applied, and which retains the nailing post in proper position within the door post. Clips 26 act as wedges between the nailable post 20 and flange 6 to force the post laterally so that reilange 1) occurs within the rabbet 21.

The opposite ends of grain door boards, for example, such as indicated at 30 may be nailed to the nailing post 20. When after repeated nailing in said post it should become splintered or split, it may be removed by simply removing the retaining strip 23, sliding the nailing post laterally and then outwardly as shown in Figure 5, and replacing same with a new one. The lining 25 need not be disturbed to make this exchange.

In Figures 7 and 8 a modified form of the invention is shown. In this modification the flange 6 of the door post is pierced and formed with a die-cut indent lug 35 which is pressed from the material and the rear edge of which is canted for reasons which will hereinafter appear. There are several' of these indent lugs formed in the flange 6 at vertically spaced intervals. In this modification the retaining strip 36 is in the form of an angle, the short leg of the angle compensating for the fact that the flange 6 of the door post is not provided with a reflange. Spaced clips 37 are secured at one edge to the inner face of the strip 36, the other margin being provided with a flange 3S which is adapted to hook behind the lug 3S and engage the canted surface thereof. The strip 36 with the clips 37 secured thereto at spaced intervals corresponding to the spacing of the indent lugs, is applied by inserting the clips between the post 20 and flange 6 so that the clips occur immediately above respective lugs. Then when completely thus inserted the strip 36 with the clips 37 is moved downwardly, when the flanges 38 will engage the canted surfaces of the lugs and pull the strip 36 in position thus holding the post 20` in place.

In Figure 9 is illustrated a modified form of the retaining strip, in this instance comprising a strip of material 40, having a row of spaced countersunk holes 41 therein corresponding to the threaded holes in flange 9 of the door post. Longitudinally along one margin, the material is bent upon itself as indicated at 42. The overall width of this thus formed strip is the same as that of the strip Z3, and the width of the folded portion 42 is equal to the space between the flange 6 and the nailable post so that when the parts are in position the strip effectively holds the nailing post in position within the door post.

An adaptation of the invention to a standard A. A. R. door post is shown in Figure l0. Such standard door post comprises an angle member comprising ilanges 45 and 46, the latter defining one side of the doorway. Flange 46 terminates in a reange 47 similar in all respects to the reflange 10 of the other views. To adapt the invention to this standard post, a Z-section is provided comprising a web portion 48, positioned parallel to flange 46, a flange 49 extending parallel to and flatwise against ange 45 and to which it is welded as at 50, and another flange 51 extending parallel to flange 45, similar in all respects to flange 9. When these two parts are welded together a door post is provided which is substantially identical to that provided in Figures 1 to 6 inclusive. The nailing post 20 to fit within this door post is identical to that shown in the other views excepting that a rear corner is rabbeted to accommodate the ange 49. Otherwise the parts are identical to the corresponding parts in the other views and accordingly carry the same reference characters. It is not believed necessary to repeat the description of these parts here.

It may be mentioned too that the direction of the corrugation in the retaining clips 26 may be reversed so that there would be less liability of the post 20 to rotate on its longitudinal axis.

From the foregoing it is apparent that I have devised a combined hollow metal door post and wooden nailing post therein which may be easily held in place and yet be very conveniently removed therefrom so that a new nailing post may replace one that has become splintered and split through repeated nailing of grain doors and the like thereto.

I claim:
